HD 106906 Stellar Debris Disk (IMAGE) University of California - Los Angeles Caption An image of the HD 106906 stellar debris disk, created by Erika Nesvold's simulation, showing the ring of rocky and icy planet-forming material rotating around the star. (The star is removed from the image, masked by the black circle.) The different hues represent gradients of brightness in the disk material; yellow is the brightest and blue the dimmest.
